On IOSV1 we have two networks that we need to reach from IOSV4. 1.1.1.0/24 1.1.2.0/24 1.1.3.0/24 The link between IOSV2 and IOSV4 is 10.0.3.0/30 The link between IOSV3 and IOSV 4 is 10.0.4.0/30 The situation: Our company runs OSPF, and we just acquire d another company that runs EIGRP. We are keeping their topology and …

First we’re going to be creating a eBGP session with IPv4 and then we will advertise routes for IPv6 Prefixes over that session. R2 is in AS 1. R3 is in AS 2. R2 has a L00pback interface with an IPv6 address of 2002:2::2/128 R3 has a L00pback interface with an IPv6 address of 2003:3::3/128 …

As you may know BGP HAS to pick a best route, and that is the route that will be put into our global routing table. Recall that our IGPs have a maximum-paths command that state how many paths can be in the routing table? BGP supports the “maximum-paths” command, however it behaves differently than it …

The reason I decided to make this post is because all other MED/Metric changing tutorials out there only include an example of one prefix. I wanted to make one that looked more realistic. Before we begin let’s overview the BGP MED attribute: MED/Metric are synonymous MED influences how your eBGP neighbors should enter your autonomous …

If you’re working with 2008 R2 Terminal servers you’ll find that on every login the default printer will be changed. This is how you fix it. Open server manager and then drill down to the “RD Session Host Configuration” menu. Right click RDP-Tcp and click properties Go to the client settings tab and confirm “Default …
Link between R1-2 is 10.0.0.0/30 link between R1-4 is 10.0.1.0/30 Link between R2-4 is 10.0.2.0/30 Link between R2-3 is 10.0.3.0/30 R1 has a loopback of 1.1.1.1/32 R3 has a loopback of 3.3.3.3/32 We want our traffic to go from router 3 (far right) to router 4, then to router 1. We need to apply this …
